Resumen del manual
Wait one (1) minute before lighting pilot again. 8. Turn control knob counterclockwise to desired heating level. The main burner should light. Set control knob to any heat level between HI and LO. CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.

Turn control knob clockwise to the OFF position. 2. Turn off all electric power to the appliance if service is to be performed. Shutting Off Burner Only (pilot stays lit) Turn control knob clockwise to the PILOT position. THERMOSTAT CONTROL OPERATION The thermostatic control used on these models differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or decreases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any heat level between HI and LO. Note:The thermostat sensing bulb measures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation location, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels. MANUAL LIGHTING PROCEDURE 1. Remove front panel (see Figure 10, page 8). 2. Follow steps 1 through 5 under Lighting Instructions. 3. With control knob pressed in, strike match. Hold match to pilot until pilot lights. 4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Follow step 8 under Lighting Instructions. 5. Replace front panel.

PILOT FLAME PATTERN Figure 24 shows a correct pilot flame pattern. Figure 25 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 25 • turn heater off (see To Turn Off Gas to Appliance, pages 12, 13 or 14 depending on your model) • see Troubleshooting, pages 17 through 19 Note:The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color. Thermocouple Pilot Burner Thermocouple Pilot Burner Figure 24 - Correct Pilot Flame Figure 25 - Incorrect Pilot Flame Pattern Pattern BURNER FLAME PATTERN BLUE FLAME MODELS Figure 26 shows a correct burner flame pattern. Figure 27 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than 1/2 the glass panel height. WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame pattern shows yellow tipping, proceed with the following instructions. NOTICE: Do not mistake orange flames with yellow tipping. Dust or other fine particles enter the heater and burn causing brief patches of orange flame. If burner flame pattern is incorrect, as shown in Figure 27 • turn heater off (see To Turn Off Gas to Appliance, pages 12 or 14 depending on your model) • see Troubleshooting, pages 17 through 19 1/2 GLASS HEIGHT Yellow Tipping 1/2 GLASS HEIGHT Figure 26 - Correct Burner Flame Pattern (Models GWN6 and GWP6 will be lower due to lower input rating) Figure 27 - Incorrect Burner Flame Pattern BURNER FLAME PATTERN INFRARED MODELS Figure 28 shows a correct burner flame pattern.
